330901-00-60-10-01-00 Bently Nevada 3300 NSv Proximity Probe

Product Overview

The Bently Nevada 330901-00-60-10-01-00 is a specialized 3300 NSv (Narrow Space Viton) proximity probe designed for applications where installation space is extremely restricted. This transducer system is optimized for use with small targets, such as shafts under 13 mm (0.5 in) in diameter, or in environments where the probe must be mounted in close proximity to other metallic surfaces. Featuring a 1/4-28 UNF thread and a 6.0-inch case length, it provides high-resolution non-contacting displacement measurements for centrifugal compressors, pumps, and high-speed rotating equipment.

Technical Configuration

• Unthreaded Length (00): 0.0 inches (fully threaded case).
• Overall Case Length (60): 6.0 inches for deep-reach access.
• Total Length (10): 1.0 meter (39 inches) integrated lead.
• Connector (01): Miniature coaxial ClickLoc connector with IP67-rated sealing.
• Agency Approval (00): Standard (No specific country-level approval required).

Technical Specifications

Installation & Maintenance

When installing the 330901-00-60-10-01-00, adhere to the recommended installation torque of 5.1 N•m; do not exceed the maximum rating of 7.3 N•m to avoid stripping the 1/4-28 UNF threads. The probe includes a Viton® O-ring which provides a reliable pressure seal in fluid-filled environments. Ensure the ClickLoc connector is kept clean and dry before mating to maintain its IP67-rated moisture protection.

Engineering Advantages

The 3300 NSv series stands out for its Narrow Space performance, effectively eliminating "sideview" interference common in standard probes when mounted in tight recesses. Its ability to operate across a wide temperature spectrum—from -62°F to +351°F—makes it ideal for both cryogenic and high-heat applications. With its MIL-STD-810G shock compliance and 304 stainless steel body, this sensor is built for long-term durability in environments prone to high vibration and chemical exposure.

Technical FAQs

Q1: What defines the "NSv" series compared to standard 3300 XL probes?
A1: The NSv (Narrow Space viton) series is specifically designed to have a smaller magnetic field, allowing it to accurately measure displacement on small shafts or in tight recesses without significant error from surrounding metal.

Q2: Can I use this probe with a standard 8mm 3300 XL Proximitor?
A2: No. The 330901 requires a specific 3300 NSv Proximitor Sensor to ensure the correct output voltage and linear range calibration.

Q3: Is the cable resistant to industrial lubricants?
A3: Yes, the FEP-insulated cable is designed to resist oil, moisture, and most common industrial solvents, ensuring signal integrity in harsh environments.
